HILLSEAL 弹簧蓄能密封圈

一、 弹簧蓄能密封圈简介

弹簧蓄能聚四氟乙烯密封件是一种U型聚四氟乙烯内装配特别弹簧的下机能密封件。由恰当的弹簧力加上体系流体压力,将其密封事情唇顶出而悄悄压住被密封的里,以发生异常优秀的密封结果。其密封事情唇有最好的短而薄的特性,从而低落了摩擦和延伸了寿命。

聚四氟乙烯是一种耐化学性优秀,耐热性优越的密封材料,可应用于绝大多数的化学流体、溶剂、和液压油、润滑油,其紧缩形变很小故可临时施展密封机能。

运用温度局限可由冷媒至300℃,压力由真空至超高压力700kg/cm2 (约70MPa),挪动速度高达20m/s。弹簧可因应差别的运用情况,选用不锈钢、 耐蚀合金等,故可应用于种种高温侵蚀流体的场所。

Spring actuator ring

.Introduction to the spring actuator ring

PTFE seals spring actuator is assembled within a U-PTFE seals special spring performance. With the appropriate spring force by the fluid pressure system, to the top of the sealing lip and gently press and hold the sealed surface to produce a very good sealing effect. The sealing lip has the best characteristics of a short, thick, thus reducing friction and longer life.

PTFE is an excellent chemical resistance, heat resistance and good sealing material that can be applied to the vast majority of chemical fluids, solvents, and hydraulic oil, lubricating oil, the compression set is small so it can be long-term sealing performance of play .

Refrigerant temperature range can be used to 300 , pressure from vacuum to high pressure 700kg/cm2 (about 70MPa), moving at speeds up to 20m / s. Spring can be used for different environments, made of stainless steel, corrosion resistant alloys, it can be used in a variety of high temperature corrosion fluid situations.

1.5mm diameter can be made to the 1.5m of the coil by Run Lion, and existing customers are using the 1.5mm spring ring.

Second, the main application

Typical applications are as follows:

loading and unloading arm rotary joint seals with axial

spray paint or other paint system valves seals

vacuum seals

drinks, water, beer, installations and equipment (such as the device valve) and the food industry seals

hydraulic cylinder rod seal is the best substitute, especially for high-pressure, high lateral loads, high speed, low friction, rotary applications where a large deflection

petrochemical, equipment, application of static and dynamic seals

automotive, aerospace industrial seals (low friction, long life)

other industrial equipment or pressure vessel seals

Third, the spring actuator ring advantages

sealing performance without the impact of lack of lubrication at start

effectively reduce the wear and friction

  by different sealing materials and spring mix, can show different sealing force to suit all application requirements

  made using special CNC processing machines, no mold costs - especially for a small variety of ring

  chemical corrosion and heat resistance than the commonly used rubber ring excellent dimensional stability, no distortion or contraction of the volume generated by the sealing performance deterioration problem

   compact structure, can be installed in a standard O-ring groove

   substantial increase in capacity and service life of seals

   ring groove can be filled with anti-pollution materials

    by sealing material for the PTFE (polytetrafluoroethylene), very clean, does not pollute the process

   low coefficient of friction, no hysteresis effect slip

   start small frictional resistance, even if down a long time or intermittent operation, able to maintain a low power

      Spring actuated seals or external pressure, static and dynamic variety of applications, the choice of V-or H-form and the spring lip seal design, which show the sealing force and the compressibility of the different deformation (as shown).

V-spring / cantilever spring

H-spring / coil spring

The size will affect the spring force spring actuator ring seal properties, friction and wear behavior; the spring determines the compressibility of the spring actuator ring for the seal lip and seal groove wear ability to compensate variation of dimensional tolerances.

V-spring actuato

威尼斯人官网开户r ring features

V-type spring actuator for static seals PTFE seals and reciprocating seals occasions

dynamic sealing lip thickness increases, giving it a longer life

This structure reduces the seal dynamic sealing surface contact area, thereby reducing the friction

resistance temperature range: -150 to 260

standard applies to pressure from vacuum to 210 kg / cm ², and the installation of special ring shape may be resistant to care back to 700 kg / cm ²

Applications

body axis reciprocating piston seal

back to the shaft seal, speeds of up to 4M / s

static seal, seals may allow greater tolerance with the unscrupulous

face seal for internal pressure or external pressure application environment

dynamic seals for temperatures up to 260

H-spring actuator ring features

spring constant high, suitable for medium and high load applications

scroll every lap average spring force

can replace the standard British O-ring groove size without modifying the

stainless steel spring, corrosion-resistant alloys can also be used

resistance temperature range: -150 to 300

standard applies to pressure from vacuum to 210 kg / cm ², and the installation of special ring shape may be resistant to care back to 700 kg / cm ².

tolerance does not apply to larger and poor seals on the heart

Applications

static seals under the shaft and piston

slow dynamic seal where the speed is lower than 3 mpm

internal and external pressure with the surface of the seal

vacuum seal with the refrigerant
